,SIPHON PUMP.

a citizen of the United States of America,

and resident or vvatertown, in. the county of Middlesex and State of Massachusetts,

have invented new and useful Improvements in Siphon Pumps, of which the following is a specification.

This invention relates particularly to a device adapted to be carried in automobiles to transfer I gasoline from one tank to another, and it has for its object to provide a device which can be inserted into a deep tank through a small opening, which is adapted to siphon a liquid from one tank to another after flow is established, which is simple and inexpensive in construction yet effective and durable in use, which cannot be disarranged by tampering and which will withstand rough "usage such as that to which tools are ordinarily subjected when carried loosely I in the tool box of an automobile.

, and

Fig. 3 is an enlarged view of the tip end.

The particular embodiment of the invention chosen tor-the purpose of illustration comprises a barrel A preferably "formed from a piece of tubing, a plunger B telescoping over the upper end of the barrel a head 0 telescoping over the lower end of the barrel, an outlet tube D extending upwardly along one side of the barrel, and a flexible tube E extending from the upper end of the outlet tube D to a point below the lower end of the barrel. The head C is preferably sweated upon the barrel A so that the two parts are integrally connected together. The lower end of the head 0 is provided with two cross-cuts F so that the inlet G is not obstructed when the head rests on the bottom of a tank. A ball valve H seats downwardly in the head G to act as a check valve. tube D is connected to the head C through the medium of a right angle coupling 1 which is threaded through the head G and thence into the barrel A thereby further locking the head to the barrel and serving as a stop to limit the upward movement of the ball valve. The tube D is preferably sweated into the coupling I and the space A. Pnavina,

- ing rin The" between the coupling and the head C, is

preferably filled with solderfas indicated at K in Fig. 2, whereby the-partsare'integrally connectedtogether. The barrel jA jand tube D are interconnected just below the normal position of the plunger vB by means otfan endless clip L; which fits around both parts,

the sides of the clip being pinchedtogether or almost together between the tube and barrel and theclip being brazed to both the tube and the barrel. A ring M is fixedly attached to the tube D within theloop N by means of an endless clip 0 which surroundsthe ring and tube and is brazed to both parts.

The plunger what larger than the barrel and a ring P is brazed in the lower end-thereof to form a guide for the plunger and also to serve as a stop adapted to limit the upward movement of the plunger by engagement with the packing ring Q which is brazed to the barrel A near the upper end. A second packing ring Q is brazed to the upper end of the barrel and the space between the two pack- S is filled with packing material R. A cap'S is brazedover the upper end of the tube of the plunger B tightly to close the upper end.

In assembling the parts the rings (Jana Q, are brazed upon the barrel and the ring P is brazed to the plunger. is telescoped over the lower end of the barrel A and the cap S is later brazed over the upper end of the plunger, the packing material R being applied before the cap S In operation the lower end of the'device is inserted into a gasoline tank or other tank from which liquid isto be withdrawn and the plunger S is reciprocated until the tubes D and E are filled and flow is established. Itthe receptacle into which the liquid is discharged is lower than the tank from which the liquid is withdrawn the flow continues siphonical; otherwise the flow may B is formed of tubing some The plunger- 1,583,176 PATENT OFFICE;

valve is required in the outlet.

narrow outlet pipe extending upwardly be inaintainedby continued reciprocation of the plunger P.

Owing to the fact that the connection between the barrel and outlet tube is at the lower end of the barrel, liquid will rise into the barrel and outlet tube above the interconnection therebetween, whereby the outlet is sealed by the liquid and no check along tliebarrel and thence downwardly also jhe'lps to make it possible to eliminate the "che'ckjvalve' in the outlet. 7

Froin' the foregoin it will be evident that this device is fool-proof, durable and highly useful as an automobile accessory foremergency use when a gasoline tank unexpectedly runs dry.

1. A device of the character described comprising a barrel having a hollow handle telescoped over its upper end and a hollow head telescoped over its lower end, said handle having a tight sliding fit with the barrel and said head being fast thereto, and

a ball valve seating downwardly in said head, said head having a cross-cut in its lower end to admit liquid when resting upon the bottom of a container.

The long 2. A device of the character described 30 comprising a barrel having an inlet at its lower end, a ball valve seating downwardly above said inlet, and'an outlet connection to the barrel near its lower end, the end of said connection extending into the barrel to serve-as a stop for said ball valve.

8. device of the character described coinprlsing a barrel, a plunger, telescoping therewith, a hollow head telescoped over the lower end of the barrel and fast thereto, o

lower end of the barrel and fast thereto, a

ball valve seating downwardly in said head, and an outlet tube extending through said head and into said barrel, thereby locking the head to the barrel.
